Well they are, but not all the people have BIG download speeds.Im waiting 5 mins to get the page loaded completely...
Use photobucket, upload ur photos there.
On your album page (main page) click on share overhead of any uploaded pictures.
On the popup get to get link code then click 2nd option (thumbnail) and save.
Then you will see IMG Thumb under the pictures, paste link here.
In there you can zoom around too i guess...
